The belief that the Earth's geological features are shaped by sudden, violent events, such as natural disasters, rather than gradual processes.
Many scientists support the theory of catastrophism to explain the formation of certain geological structures.
Catastrophism is formed from "catastrophe" (from Greek "katastrophē", meaning overturning or sudden change) and the suffix "-ism" (meaning a doctrine or belief). The term refers to the belief that the Earth's geological features are shaped by sudden, short-lived, and violent events.
Think of 'catastrophe' as a sudden 'overturning' or change, and '-ism' as a belief system — catastrophism is the belief in sudden, dramatic changes in the Earth's geology.
